Echidna

Echidna is a giant, flying, snake demon that both Nero and Dante fight. In snake form, she resembles a giant snaake with a few feathery frills around the neck and multiple eyes on the head being the only diference between it's and a regular snakes appearance. However, the head "unzips" in four places down the head and this reveals Echidna as a huminoid, female with glowing eyes and no lower body (or it is at least inside the snake portion) with a pair of red plumes on her head that combine to form the tounge of the snake. she appears to be able to generate eggs of some sort and eject them from pores on the body. Dante (in regular fashion) responds by kicking a bunch of them into the forest she is hovering over, which all ricochet off the trees in a complex manner that leads them to hit her. She then tries to eat Dante, but Dante forces his way out of her mouth and fights her.
